Personal life

McLoughlin was born on 7 February 1990, in County Offaly, Ireland. His mother is Florrie McLoughlin (born 1969) and is Roman Catholic. He is the youngest of five siblings, having two older sisters (Allison and Susan) and two older brothers, Malcolm and Simon.

He was the former drummer of an indie heavy-metal band named Raised to the Ground. In the late 2000's, he graduated High School with a degree.

In the early 2010's, McLoughlin dropped out of college after two years whilst studying Music Technology in Limerick, Ireland. However, after meeting a person on Interpals, he decided to study English. He finished up college around fall 2014, the same year that his channel reached 1 million subscribers.

He started dating Danish YouTuber Wiishu around early 2015 and she previously lived with him. Fans speculated that the pair had broken up, with Jack confirming himself via Twitter that they did split in August 2018.

The Jacksepticeye Foundation was established on January 30, 2017.

Origin of the Name

In Ireland, "Jack" is a common nickname for the name "Sean", and both his mother and friends called him this. His friends started calling him "Jacksepticeye" after a football accident where he got an eye laceration from a friend's glasses. According to him, the wound bled for quite some time and became infected after a few weeks, hence the name "Jacksepticeye". (Septic is a medical term referring to a systemic infection).

Channel history

Jack created his YouTube channel on February 24th 2007, although he didn't start making his own videos until November 2012, his very first upload being a Metal Gear Solid 4 impression on Solid Snake. According to Jack in a 2017 video, he originally wanted the channel to be dedicated to impressions.

Whilst playing Battlefield 3, Jack searched for tips online and came across LevelCapGaming. Jack was also a fanboy of Markiplier and PewDiePie, becoming part of his inspiration to start his own channel. Lacking friendships and living in a remote area, he turned to YouTube so he could create an online community, despite being pressed for time to make videos since he was also studying for exams in college. In September 2013, he entered PewDiePie's shout out competition and was one of several channels who won, where he went from 2,000 to 15,000 subscribers and pounced upon the opportunity to improve. Mark noticed Jack by writing on Twitter that he had entertaining videos, resulting in their first ever collaboration being "Gmod Sandbox w/ Markiplier | DON'T WORRY....WE'RE SCIENTISTS."

From 2012 until 2014 Jack lived beside his parents in a cabin in the countryside, resulting in issues with his internet affecting his uploads. He had to use a camera as his microphone and attempted to hide his Irish accent by pretending to be American for fear of being made fun of.

In 2014, he moved to an apartment in Athlone for better internet access. He graduated from college that same year and earned a degree in Hotel Management. In 2016, Jack hired Robin as an editor. For the first time in five years in October 2017, there were no scheduled uploads for a week due to Jack touring with the Game Grumps.

Jack kick started 2018 with his motto, Positive Mental Attitude ('PMA' for short), which turned into a merchandise line released in August 2018. In July 2018, he took a week long break suffering from burn out and moved to L.A. for an extended break from July 12th until October 12th 2018. From July 20th 2018, he has decreased his uploads from two per day to one per day.

Jack focuses on game plays on a variety of different games, from indie to horror to upcoming releases, and occasionally vlogs. He has recently wanted to branch off into skit comedy. He is known for his loud, bouncy but caring personality and constant positivity, but tones down to seriousness on some occasions when something needs to be talked about. He shows his appreciation for his fanbase multiple times, such as making a subscriber milestone video thanking them.

Opportunities

As Jack got more well known for his videos, he earned various opportunities worldwide, such as attending Indy Pop Con in 2015, Insomnia 62 in Birmingham, UK in December 2015 and PAX East and PAX West every year in America. He dyed his hair green alongside Markiplier in September 2015 for charity. In July 2017, he co-hosted the D23 Expo Level Up! event in California alongside YouTuber Strawburry17. Jack was a special guest and antagonist for Scare PewDiePie: Season 2, which was eventually cancelled due to Felix making offensive jokes. In late September 2017, Jack began his very first tour How Did We Get Here? and in October 2017, he toured Europe with the Game Grumps for Ready Player 3.

He was interviewed on the Late Late Show in Ireland on February 23rd 2018. In May 2018, Jack uploaded a video of him playing Deadpool with Ryan Reynolds. Over the course of seven charity streams in 2018, Jack and his fans have raised over $1.1 million for charity. In October 2018 he unveiled his and Mark's own clothing brand, Cloak. In November 2018, he interviewed Aquaman lead actor Jason Momoa and on December 6th 2018, he presented an award for Best Narrative at the Video Game Awards 2018.
